  • Error detection on the transport channel and indication to higher layers
  • FEC encoding/decoding of the transport channel
  • Hybrid ARQ soft-combining
  • Rate matching of the coded transport channel to physical channels
  • Mapping of the coded transport channel onto physical channels
  • Power weighting of physical channels
  • Modulation and demodulation of physical channels
  • Frequency and time synchronisation
  • Radio characteristics measurements and indication to higher layers
  • Multiple Input Multiple Output (MIMO) antenna processing
  • Transmit Diversity (TX diversity)
  • Beamforming
  • RF processing.
